In the very first image released by the BBC, we see Capaldi standing next to Jenna Coleman, who plays the Doctor's companion Clara Oswald, on set while reading from a script.

While Whovians were probably hoping to see what the new Doctor would be dressed like, we will unfortunately have to wait a little bit longer to check out his new style.

Capaldi seems to be wearing Matt Smith's costume of a purple overcoat, waistcoat and shirt– although the bow tie is missing, as Smith threw it on the floor before he regenerated.

This means that the first episode of the new series will pick up from where the Christmas special left off.

In an emotional episode, Smith regenerated into the form of Capaldi, whose first word was 'Kidneys!' as he gripped his stomach in pain.

He then asked a confused Clara if she knew how to fly the Tardis.

Capaldi was announced as Smith's successor last August, becoming the oldest Doctor ever aged 55.

His first episode, written by Steven Moffat, is in a Victorian setting, and features appearances from Madam Vastra, Strax and Jenny as well as welcoming in Capaldi.

The Thick Of It actor, who is keeping his Scottish accent for the iconic role, arrived on set in Cardiff to start his stint as the Doctor and said: "New job, first day, slightly nervous. Just like the Doctor, I'm emerging from the TARDIS into a whole other world."

But however nervous Peter gets, he's already gone through pretty much everything else that could go wrong on other shows.

During filming for his latest show The Musketeers, Capaldi suffered a bit of a cringe-inducing injury.

He explained: "I myself suffered a nasty dislocated thumb, but embarrassingly not from swinging a sword around. Instead, my injury came from a domestic the cardinal was having with milady, Maimie McCoy.

"I threw her against the wall not realising I'd caught my thumb in her large frock. I felt a jab of pain. And when the director said 'cut' I looked down and saw my thumb was on the wrong way round. Nasty. Instinct took over and I shoved it back - which made my eyes water and my knees weak."

At least now he'll have a sonic screwdriver for emergencies.
